I'm having a difficulty performing a backtrace following the information given on Inkscape.org, and what I found on Launchpad. The result is "no stack"??? I am using Ubuntu Karmic, likewise 0.47 pre 4 r22446 (built Oct 14, 2009) which overwrote my official package, and also 0.46 +devel (built Oct 26, 2009). If I could have someone tell me strictly what I am supposed to type into the terminal in order, I would greatly appreciate it and I would be more than happy to submit bug reports. Many thanks.
